[texts]Successes and Pending Tasks of Matlab Simulink-Successes of Matlab Simulink
In this paper, the main advantages of Matlab Simulink were demonstrated on the basis of research works developed over the past few years. Simulink presents an open code that allows building researchers develop new tool boxes. These tool boxes give us the flexibility to improve building simulation considering the new parameters that are under investigation. Based on the open code and research works, more recent researchers could define, step by step, the effect of this heat and mass transfer over...

[texts]13. Torque Minimisation.full
DTC of an induction motor fed by a voltage source inverter is a simple scheme that does not need long computation time, can be implanted without mechanical speed sensors and is insensitive to parameter variation.In principle, the motor terminal voltage and current are sampled and used to estimates of the flux position and the instantaneous error in torque and stator flux magnitude a voltage vector is selected to restricts the torque and the flux error with in their respective torque and flux hys...

[texts]Control-Integrated Design by Theoretical Simulation for a Torque-Actuated 6-SBU Stewart Platform
A design algorithm has been proposed for a Stewart platform with six legs, each having a ball-screw at the middle and powered by a torque motor at the bottom. When a motor shaft rotates, the leg extends or collapses and the axis could rotate about a spherical joint supporting the motor. Consequent actuation from all the legs through a universal joint at the top of each causes the platform to change its pose...

An adaptive filter is a filter that self-adjusts its transfer function according to anoptimization algorithm driven by an error signal. Adaptive filter finds its essence inapplications such as echo cancellation, noise cancellation, system identification and manyothers. This paper briefly discusses LMS, NLMS and RLS adaptive filter algorithms forecho cancellation. For the analysis, an acoustic echo canceller is built using LMS, NLMSand RLS algorithms and the echo cancelled samples are studied usi...

[texts]Microcontroller Based Novel Dc-to-Ac Grid Connected Inverter Topology
The conventional line commutated ac-to-dc converters/ inverters have square-shaped line current which contains higher-order harmonics. Moreover, it requires a costly and bulky dc inductor or choke. The line current with the high harmonic contents generates EMI and therefore itcauses more heating of the core of distribution or power transformers. Alternatively, PWM based inverters using MOSFET/IGBT switches can be used for the above purpose...

[texts]Space Vector Pulse Width Modulation Schemes for Two-Level Voltage Source Inverter
Space Vector Pulse Width Modulation (SVPWM) method is an advanced, computation intensive PWM method and possibly the best among all the PWM techniques for variable frequency drive applications. The SVPWM is an alternative method for the determination of switching pulse width and their position. The major advantage of SVPWM stem from the fact that, there is a degree of freedom of space vector placement in a switching cycle...
